Due to constant development and decline on Seoul areas the Seoul government is pushing various policies to regenerate declined Seoul areas. Theses various policies lead to land-use changes around numerous Seoul districts. This study aims to create prediction model which can foresee future land-use changes and while doing so, tried to derive various influential factors which leads to land-use changes. To do so, various open-data from national departments and Seoul government have been collected and implemented into random forest algorithm. The results showed promising accuracy and derived multiple influential factors which causes land-use changes around Seoul districts. The result of this study could further be implemented in policy makings for the public sectors, or could also be used as basis for studying gentrification problems happening in Seoul Area.

Conversion of the building can be a core strategy to activate the urban regeneration. Especially in the decayed district, the conversion or retrofit of old building can be a core catalyst to stimulate the urban regeneration. Throughout the case study, a conversion from office to dwelling, there were figured out the design strategies to respond to spatial, functional requirements. The results are as follows ; 1) The main design strategy is to articulate the space by embedding the wall, mass in the rectangular space. 2) to respond to the small size of space, the flexible, movable wall system Is adopted. This gives the selectiveness to the use of space. 3) to secure the livability of interior space, the buffer zone, a terrace space, is fully utilized. This space acts as thermal buffer zone as well as a semi-interior space.

As a pilot project of the National Spatial Data Infrastructure, "Quality upgrade of continuous cadastral map and Conversion of land use zoning map" is performed last year. In this study, for the following main project, its result is analyzed and problems occurred on the way carried out are extracted. The area change before and after conversion is compared, and relationship with the continuous cadastral map is analysed on the data of Ansung-Si. And than, systematic improvement method is suggested based on that problem.

This study focuses on some institutional improvement for revitalization of change in building use of officetel to lifestyle lodging industry. First as analysis method, this study establishes a failure factor for change in building use of officetel to lifestyle lodging industry. Second, analyzes an urgent importance to improve it in aspect of a legal institution or management for revitalizing a change of building use of officetel to lifestyle lodging industry. As a result, a failure factor of change in building use from officetel to lifestyle lodging industry is deducted in 4 articles with 13 detailed index. As a result of AHP, 'existing contractor's 100% agreement condition' is the first place, 'commercial /semi-residential area in zoning' is the second place, 'relative cleanup zone' is the fourth place, 'late changes of building use by a complex licensing procedure' is the fifth place, 'operational risk of consignment' is the sixth place, 'deficiency in publicity of related institution' is the eighth place, 'lack of concept in lifestyle lodging industry of building code' is the ninth place, 'basic constructional condition such as parking lot sewage and fire protection system' is the tenth plce, 'installation of ventilation facility' is the eleventh place, 'installation of bathroom and shower room in each room' is the twelfth place, 'installation of kitchen facility' is the thirteenth place.

The purpose of this study is to find the characteristics of space utilization and the problems that follows after converting in a new developmental residential area. This study used the content-analysis method and analysis was made on the floor plans for 95 different conversion cases. Above all, 190 unit plans (the unit plans for conversion before and after) were analyzed. The results of this study were as follows; 1) There were 8 types of conversion according to such usages as residential, commercial and residential-commercial buildings. 2) In the case of conversions, from residential to commercial, there was a tendency each floor was integrated to exclusive use for commercial or commercial with small portions of residential usage. And in the case of conversions from commercial to residential, there was a tendency that all space of each floor were changed to exclusive usages for residential purposes. 3) In case of usage conversion from commercial to residential, there were constraints for balcony installation, because of its original lot-structure and building equipments. Also, when the basement was converted for residential purpose, there was no possibility for an extra lighting or ways to ventilate the area.

In urban planning and architecture, there has been emerging paradigm of regeneration, taking place of demolishing first, and new development next principle. Retrofit and remodeling, thereby, became important. The purpose of the research in to examine a reused space with new function. The target space was the former slaughterhouse in the ailing district of the Bologna City with ever increasing vandalism and fear caused by empty buildings, which was regenerated into a culturally affluent area, such as cultural facilities including cinema, gallery, art school cluster along with elderly club and child care center nearby. Through this regeneration, more affluent life opportunity was provided for citizens and local residents. This case study shows how old the building and interior space have been transformed to accommodate contemporary needs, while preserving historical features.

Recently, due to the location of residential complexes in commercial areas of large cities, the urban function is shifting from commercial to residential.In order to improve the use volume system in the commercial area of Daejeon Metropolitan City, the system of special and metropolitan cities was compared and analyzed, and problems were derived by analyzing 8 cases. First, use classification of mixed-residential buildings, Second, unbalance of urban planning for functional loss of commercial area, Thrid, damage on urban environment due to difference of development density. Accordingly, improvement measures include First, securing the ratio of residential function and mixed use at least 10%, Second, securing urban competitiveness by inducing facilities that combine various uses and functions. The overall floor area ratio of housing is applied, Third, the development density is presented through the establishment of the district unit plan and consultation.

In general, the decay of the residential district has been considered a phenomenon of old towns. But now it has become a problem of new development areas too, which have been a cause of the decay of old town. This study aims to investigate the decay of the residential district in the new development area. The survey site was Dunsan, a town-intown of Daejeon metropolitan city. The findings were as follows (:) 1) even in the new development area, a high level of vacancy ratio was evident. ; 2) among the buildings above ground, 1st floor showed the highest vacancy ratio, which means the 1st floor was allotted to too many commercial facilities relative to the buying power size in this district. ; 3) there were many conversions in response to the decay of the district, from residential to commercial, and commercial to residential. ; and 4) the allocation of each type of conversion showed a spatial pattern.

The concept of customer utility, which affects customer's adoption, is important to understand the process of technology diffusion and substitution regarding multiple generation technology. This research defined the concept of attribute-based customer utility and developed a model for measuring attribute-based customer utility. Based on the literature review and modeling, we provided the definition and a model regarding customer utility and the accuracy of the model is verified through a case study of the semiconductor industry. Customer utility for a multiple generation technology needs to consider changes by generation, or time within the same generation, and is defined as the summation of both technological and economic utilities. In addition, we can model the measurement of customer utility after converting technological and economical attributes into utilities. This research is valuable in understanding not only customer utility as a driver of customer adoption, but also for establishing technological strategy after forecasting diffusion and substitution paths based on customer utility.
